John, I'll try - I drilled a 3/8" hole in a Rosewood pen blank. Than I Turned a piece of Maple to a 3/8" dowel and glued about a 2" piece into the Rosewood blank. I cut off about 1 1/2 inch piece. I centered the 3/8 inch dowel that I had glued into the piece of Rosewood between centers on the lathe and turn the whole thing down to three-quarter inches. Then I took my Maple blank and glued some pine scabs on the edges. Now I was able to drill a three-quarter inch hole in the very center of my Maple blank. Now I glued the 3/4" Rosewood dowel with a maple center into the 3/4" hole I had in the maple blank. After the glued in piece had cured I trimmed off the pine scabs and you have seen the results after it was turned. The difficult part is keeping everything centered. Have fun.
